EXTINGUISHING MEANS FOR MATCH-BOX-FILLING MACHINES.

Specification of Letters Patent.

Patented June 1, 1909.

Application filed December 20, 1907. Serial No. 407A2.

To all whom it may concern:

Be it known that l, CARL l lninnoLo AN- DERSSON, a subject of the liing of Sweden, and resident of corner of Oster and Soder gatorna, building-lots Nos. 633 and 634, Ninersborg, in the Kingdom of Sweden, have invented certain new and useful improvements in Extinguishing Means for Match-Box-Fillin Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

l/Vhen matches are filled in boxes by means of such machines, in which the matches are mounted in magazines, from which they are delivered in suitable portions and filled in the boxes, it frequently happens that the matches, while being divided in portions, catch fire, all matches in the magazine then burning up.

This invention relates to means for extinguishing the fire in such magazines, before it has had time to spread in any degree worth mentioning, and in this manner to reduce the number of burned matches to a minimum.

The invention principally consists of a pipe communicating with a tank containing a liquid or gas suitable for effecting the ex tinguishing operation as for instance water, carbonic acid, steam etc. which pipe, at a suitable point near the magazine, is provided with a stop-cock of suitable construction, which can be opened by a spring, a weight or the like, which opens the cock, when a thread of combustible material, extending in front of the heads of the matches and counteracting the tension of the spring or the weight, is burned off. The end of the said pipe is provided with a mouth piece of suitable size and shape, which is applied to the match magazine immediately above the point where the said thread is located, the said mouth piece being provided in the side, facing the matches, with holes, through which the liquid or gas can escape.

In the accompanying drawing Figure 1 is a front view of a match-magazine provided with the said extinguishing means. Fig. 2 1s a section on the line AB of Flg. 1. Fig.

3 is a front view of a part of the magazine and the said means on a greater scale, and Fig. 4 is a section on the line CD of Fig. 3.

A pipe 4 or the like communicates with a tank for a suitable liquid, located at such a level, that suitable pressure of the liquid is attained. The said pipe 4 is connected with the match-magazine 2 and at the connection point provided with a mouth-piece 1, in the side of which, facing the matches, holes 3 are provided, through which the liquid or gas can pass into the spaces between the matches.

The pipe 4 is shut off by a cock 5, which, when closed, has the position shown in the drawing. An arm 6, fixed to the plug of the cock, is balanced by the tension of a spring 7 and of a thread 10 of a combustible material. The said thread 10 passes from the arm 6 around tightening rollers 12 and, immediately about the dividing knives 9, between the heads of the matches and the back plate 11 of the magazine and then back to the arm 6. If now the matches catch fire at the dividing knives 9, the thread 10 will burn off and acted upon by the spring 7 the arm 6 is swung sidewise, whereupon the liquid or gas escapes through the holes 3 and prevents the fire from spreading to matches located above. At the same time as the cock is opened the operator is alarmed by a bell 8, hanging from the spiral spring 7, so that he can shut the cock and stop the machine for cleaning and removing of burned matches. The described means may be provided also in other machines where the matches are located in magazines, partitions or the like.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a match box filling machine and in combination, a match magazine, a hopper connected thereto for delivering the matches, one side of the said hopper being provided with a series of apertures, a hollow faced mouth piece placed against the exterior of the said hopper so as to cover the said apertures therein, a pipe leading to the said mouth piece, a cock in said pipe, a piece of combustible material secured in the lower portion of said hopper, passing through the same and adapted to maintain the said cock in its closed position and means operative upon the parting of the said pieces of combusti le material for opening the said cock.

2. In a match box filling machine and in combination, a match magazine, a hopper connected thereto for delivering the matches, one side of said hopper being provided with a series of apertures, a hollow faced mouth piece placed against the exterior of the said opper so as to cover the said apertures therein, a pipe leading to the said mouth piece, a cock in said pipe, an arm connected to the spindle of the said cook, a piece of combustible material secured in the lower portion of the said hop er, passing through the same and connecte t0 the said arm to maintain the said cock in its closed position, and means operative upon the parting of the said piece of combustible material for opening the said cock.

In a match box filling machine and in combination, a match magazine, a hopper connected thereto for delivering the matches, one side of said hopper being provided with a series of apertures, a hollow faced mouth iece placed against the exterior of the said hopper so as to cover the said apertures therein, a pipe leading to the said mouth piece, a cock in said pipe, an arm connected to the spindle of the said cook, a string connected at one end Within the lower portion of the said hopper, passing through the hopper and connected at the other end to the end of the said arm to maintain the said cock in its closed position, and a spring for actuating the said arm to open the said cock on the breaking of the said string.

4. In a match box filling machine and in combination, a match magazine, a hopper connected thereto for delivering the matches, one side of said hopper being provided with a series of apertures, a hollow faced mouth piece placed against the exterior of the said hopper so as to cover the said a ertures therein, a ipe leading to the sair mouth piece, a 000 i in said pipe, an arm connected to the spindle of the said cook, a string connected at one end within the lower portion of the said hopper, passing through the hopper and connected at the other end to the end of the said arm to maintain the said cock in its closed position, a spring for actuating the said arm to open the said cock on the breaking of the said string, and a bell connected to the said spring to give an audible indication of the opening of the said cock.

In Witness whereof, I have hereunto signed my name in the presence of two subscribing Witnesses.
